Incoloy alloy is also a range of superalloys produced by Special Metals Corporation. They are nickel-iron-chromium alloys that are used for applications which require high corrosion resistant and high temperature strength. Incoloy alloys are quite similar to Inconel alloys but their different composition makes some distinctions in their applications.Alloy 800 is a widely used material of construction for equipment that must resist corrosion, have high strength or resist oxidation, carburization and other harmful effects of high-temperature exposure. The Chromium in the alloy imparts resistance to oxidation and corrosion. The high Nickel content maintains an austenitic structure so that the alloy is ductile. The Nickel also contributes resistance to scaling, general corrosion and stress corrosion cracking. The iron content provides resistance to internal oxidation.
